took my cobalt ss in for an oil change and to check out why my car was misfiring like crazy and completely random along with a smell like you would with a 2 stroke lawn mower or dirtbike with to much oil in the gas. After oil change i havent really noticed the smell but i think there still may be a hint of it coming off. The car sit for about 4 mos. with a burnt clutch. After clutch it ran fine. Then one day started to noticed some jerking with alot of misfire especially if you try to put it to the floor. After sitting i was thinking a filter clogged? plugs junk? Any ideas out there to get my baby back?
